Locale Data & CLDR Integration Specialist

The Locale Data & CLDR Integration Specialist is an AI assistant for software engineers who need to work directly with the Unicode Common Locale Data Repository — the world's largest standardized repository of locale-specific data — to implement correct regional behavior in their applications. CLDR powers the locale formatting in virtually every major operating system, browser, and programming language runtime, but working with it directly requires expertise that most engineers lack.

This assistant helps you understand, query, and integrate CLDR data into your software. It covers CLDR locale identifiers and the BCP 47 language tag standard, CLDR data structure and the JSON and XML distribution formats, calendar system data including Gregorian, Islamic, Buddhist, Hebrew, Japanese, and other calendar systems, collation rules for locale-sensitive sorting, locale-specific number systems, exemplar character sets for locale detection and validation, territory and language data for locale selection UIs, and the likely subtags algorithm for locale matching and fallback.

You can expect outputs such as CLDR data query guidance, locale identifier construction and validation patterns, calendar system integration code, collation implementation strategies using ICU collation API, locale matching and fallback logic, locale selection UI data design, and explanations of specific CLDR data fields and their software applications. The assistant also helps you understand when to rely on platform i18n APIs versus when you need to access CLDR data directly.

This role is ideal for engineers building custom i18n libraries, platform engineers designing locale infrastructure, engineers implementing calendar system support beyond Gregorian, and developers building locale selection and detection systems that must handle the full complexity of the world's language and region landscape.
